Radio Liferay Episode 60: Performance and Permissions with Preston Crary
An episode on the "Per" things: Performance and Permissions. I spoke to Preston Crary, who amazingly was not mad at me for losing an earlier recording.
We're talking about these (and more) topics
- We open with the attention to detail that's required for working on performance tuning and some short conversation about this topic.
- Sadly, there's not often a single silver bullet, but many areas of dust.
- Sometimes the fastest code is not the most optimal
- Continuing with Preston's work on Permissions:
- ResourceBlock is deprecated, and there's an easy migration path
- an example upgrade path for bookmarks
- The usecase for Resources, ResourcePermission, and ResourceBlocks (as they're not at all visible on the UI)
- Preston's way through Liferay from Support to working on the topics that he's now working on
- The new API for Permissions - and the documentation is also done already (as of me writing this article, not yet published, but available on github - should be a matter of days or hours)
- And an example: The implementation of this API in Journal
- more documentation on registering and checking permissions
- Should you implement your own permission system? (and how the answer to this question might change in 7.1)
- Upgrades are being performance tuned. I smell a future episode coming up. Paging the team that is working on this area
- The remarkable memory savings that refactoring the UserBag introduced
- What happend during login
- Passwords are PBKDF2WithHmacSHA1/160/128000 hashed, a deliberately expensive password hashing algorithm.
- LPS-75747 and an update to my hardball question: Document Library's default.xml is still in core, can't be updated through a module, just through an ext.

Radio Liferay Episode 51: Ray Auge - Modularization I - Motivation
Another Devcon "private" session - I missed his presentations, but got the summary right when he was done: Ray Augé took the time to answer all sorts of questions about the Modularization in Liferay 7. In fact, he answered so many questions that we made it a 2-episode recording. This week it's about the motivation for modularization: What problem does it solve? Next week will be more technical, telling you about the implications of the updated architecture to your code.
As we recorded this on site at Devcon, you'll hear more background noise than usual - As usual, Auphonic did their best to clean the recording, and they did a great job.
- OSGi in Liferay 6.2 vs Liferay 7.0
- Modularization of Liferay 7.0
- Surprisingly (not!), modularization is not yet fully done, but it came a lot further than expected initially
- How much do you have to re-learn to build plugins for Liferay 7
- James: Community Roadmap Talk from Devcon (note: Ray also had several presentations at Devcon, you'll find his recordings there as well)
- Now everybody should be able to work the same way: Internally in Liferay's core as well as externally, in the plugins.
- Ant vs Maven vs others? What's the story with Liferay's supported Build environments? More energy will go into build tools other than the SDK
- Of course we cover a release date :) I'm getting a very rough one from Ray :)
